Reverse pinch

Reverse pinch

A reverse pinch (sometimes also called “unpinch”) refers to a motion used to interact with multipoint touch screen interfaces, such as that employed on the Apple Inc. iPhone device [http://www.apple.com/iphone ] . The motion involves spreading two fingers (or thumb and finger) apart to signal the device to perform an action such as enlarging a picture or zooming in on an image. The opposite motion, i.e., pinching together the thumb and finger, leads to reducing the size of the image.
